Risk Analysis of The Underpass Construction Project on HM Yamin Street Medan Timur District (Case Study: Structural Works)

Abstract

The construction industry is widely recognized as one of the sectors that makes a major contribution to a nation’s economic growth, since it supports infrastructure development, employment generation, and broader economic activity. However, despite its strategic importance, risk evaluation in construction project activities is often not given sufficient attention, even though risks can strongly influence project progress and performance. When risks are not identified and managed properly, their effects may extend beyond delays and additional costs, ultimately influencing the quality of the final outcome as well as client satisfaction. For this reason, the analysis of risk factors affecting project progress is essential in order to support the success, efficiency, and sustainability of construction projects. In this study, the purposive Sampling method was employed to obtain data from respondents considered to have relevant knowledge and experience regarding the project conditions. Based on the findings, the identified risks can be grouped into three categories, namely high, moderate, and low risk. Among these, material damage and loss were found to fall into the high risk category, indicating that they have the greatest potential to disrupt project implementation. To reduce the impact of this risk, several mitigation measures are proposed, including strengthening project security personnel, improving the organization of materials, and arranging material placement in effective and secure storage facilities. Together, these actions provide a practical basis for reducing uncertainty and improving project control during construction implementation.
